Support for S3c2440 processor

Rajam AP
Hello all 

We have bought MINI2440 development kit and we are planning to use the same
processor and Linux platform for our new device. We have been informed by
Samsung that this processor will not be supported soon and it is better to
not use in any new product. We also have SMDK2450 development kit and Linux
on this board has lots of interface(s) issues. 

Any expert opinion on whether we can proceed with MINI2440 for Sw
development would be highly appreciated. 

Regards

What kind of software development do you mean? Kernel or
userland/application? For userland/application I see no reason why not
starting development on your mini2440 (even if you change later on to
another processor). Its (mostly) independent of the processor it runs on. I
don't know the 2450 yet. But if you want to do some development in the
kernel area, you should start with the new processor and forget the old
one.

As Juergen stated you can develop you applications on every platform. Then
just recompile for other type of CPU (2450 is ARM926) so never like 2440.

Thanks for the response. I meant user application in Linux. I do not want/
have time to do kernel related updates. But the basic Linux kernel is
giving problems in S3C2450 based board which includes ECC errors being
reported in NAND, no LCD and touch screen interface and no camera interface
etc., 

But the kernel that came with mini2440 has all the basic interfaces up and
running.

So you need to update also kernel (or put some development effort to it).
Otherwise switching to other platform (2450) would be impossible ;). Bad
new is that also mainline kernel AFAIK doesn't have support for 2450 :(.

Hi Rajam,

if the S3C2440 comes with all interfaces you need for your application and
the S3C2450 also supports these interfaces, then you really can start with
your application development on the mini2440.
In the meantime the support for the S3C2450 may occur in the kernel, so you
can switch later on to this new processor.

Hi 

As suggested we have started with the application development using
MINI2440 and we will plan to later port it to S3C2450 based board.
Hopefully we should be able to ride through this ....

Thanks a lot for all the responses and sharing,
